What is toluene used for?

Toluene is an important raw material (intermediate) for the manufacture of a large number of intermediates, such as toluene di-isocyanate, which is used for the production of polyurethanes. Polyurethanes are a set of versatile products which are used to make the foam in furniture, mattresses, car seats, building insulation, coatings for floors and furniture and refrigerators, sports equipment, etc.
Toluene is also found in some solvents, such as some used in paints and glues, in gasoline (as an octane booster) and is also used to produce explosives. This is far from exhaustive; for more, see the section Aromatics in everyday life.
